1/4" Threaded Cobalt Drill Bit
Standard 1/4-28 Thread

New- USA Made

  Length= 3/8"

Type "D" adapter drills are made from M42 8% cobalt high speed steel and are manufactured to NAS 965 Type "D" specifications with 135° heavy duty split points and surface treated for drilling hard, tough high tensile strength materials.  When drilling low tensile strength materials, the Type "D" cobalt drill will have a significantly greater tool life than the NAS 965 Type "B", high speed steel adapter drill, resulting in a much lower cost per drill.
